Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 4 generators on 32 points:

(1,2,4,5)(3,7,8,6)(10,13)(14,16)(17,18,23,28,21,26,22,27)(19,29,31,32,20,24,30,25);(2,5)(6,7)(10,14)(12,15)(13,16)(17,19,22,30,21,20,23,31)(18,24,27,32,26,29,28,25);(9,10,11,13)(12,16,15,14)(17,20,21,19)(18,25,26,32)(22,30,23,31)(24,27,29,28);(1,3,4,8)(2,6,5,7)(18,26)(24,29)(25,32)(27,28)
